BACKGROUND

An X-ray is an electromagnetic wave having a wavelength from about 0.01 to about 100 angstrom (Å) and can be used to obtain the internal structure of an object. Therefore, X-ray devices are widely used for photographing the inside of a living body or for common non-destructive industrial inspection.

The basic principle of a photographing device using X-rays is to transmit X-rays emitted by an X-ray tube (or an X-ray source) to a target object and detect a difference in the intensity of the transmitted X-rays via an X-ray detector and thus obtain the internal structure of the target object. When an X-ray apparatus includes a plurality of X-ray detectors, it is necessary for a user to check which of the X-ray detectors is mounted to a frame of the X-ray apparatus or a direction the corresponding X-ray detector is mounted to the frame of the X-ray apparatus.

The X-ray apparatus may determine whether the X-ray detector 1220 is mounted to a table-type mount according to the table-type scan mode selected based on the user input.

The X-ray apparatus may determine that the currently sensed position of the X-ray detector 1220 is the stand-type mount 1230 instead of the table-type mount. Therefore, the X-ray apparatus may determine whether X-ray scanning may be performed according to the scan mode selected based on a user input, that is, the table-type scan mode, based on the current position and the mounting direction of the X-ray detector 1220. In the embodiment shown in FIG. 12B, the X-ray apparatus may determine that the X-ray detector 1220 is currently mounted to the stand-type mount 1230 and determine that X-ray scanning may not be performed according to the table-type scan mode selected based on the user input.

The X-ray apparatus may display a user interface 1210B that includes a scanning impossible icon 1250.

Referring to FIG. 12C, the X-ray apparatus may receive a user input for selecting the table-type scan mode icon 1212 via the user interface 1210 and, according to the table-type scan mode selected based on the received user input, may determine the current position of the X-ray detector 1220. According to an embodiment of the present disclosure, the X-ray apparatus may determine whether the X-ray detector 1220 is mounted to a table-type mount 1232.

In the embodiment shown in FIG. 12C, the X-ray apparatus determines that the currently sensed position of the X-ray detector 1220 is the table-type mount 1232 and X-ray scanning may be performed according to the table-type scan mode selected based on the user input. In this example, the X-ray apparatus may display the scanning possible icon 1240 on a user interface 1210C.

Referring to FIG. 12D, the X-ray apparatus may receive a user input for selecting the portable-type scan mode icon 1213 via the user interface 1210 and, according to the portable-type scan mode selected based on the received user input, may determine the current position of the X-ray detector 1220. According to an embodiment of the present disclosure, the X-ray apparatus may determine whether the X-ray detector 1220 is mounted to neither the stand-type mount 1230 (refer to FIGS. 12A and 12B) nor the table-type mount 1232.

In the embodiment shown in FIG. 12D, the X-ray detector 1220 may be mounted to the table-type mount 1232. Therefore, the X-ray apparatus may determine that the X-ray scanning may not be performed according to the portable scan mode selected based on the user input and display the scanning impossible icon 1250 on a user interface 1210D.

In the embodiment shown in FIGS. 12A through 12D, the X-ray apparatus displays whether the X-ray scanning may be performed according to a scan mode selected based on a user input by using the scanning possible icon 1240 or the scanning impossible icon 1250, thereby reducing effort of a user to determine a current position and a mounting direction of the X-ray detector 1220 and improving user convenience.
